• Leave the battery in or out

  I guess this applies to all laptops, but since I have my T400 connected almost exclusively to food, should I leave the battery in or out?

  In other words, is the aging of the battery faster because it is in a constant state of charge (in) or it would last longer if I removed it while the computer connected to the power supply?

  Thank you.

  leave the battery in won't hurt, if you are not using your battery which keep well the battery around 40 to 60%. Then go into your power manager thinkvantage in respect of the maintenance of the battery. Set the level to minimum load to near 20% and maximum level between 40 and 60%.

  Now unplug your power supply, then run the battery around 60%, then reconnect your power back. This should maximize your battery life.

  Also, if you use the 65 watts, the laptop adapter speed Accelerator (CPU speed will be capped) If you do not have the battery plugged.

• E4200 Intel 5300 on Lenovo T400 does not connect to N 2.4 ghz or 5 GHz

  I searched the problem as well I can I

  to not eval, I can't have the Intel 5300 on a Lenovo T400 to connect to N or Radio

  I tried every combination possible parameter on the E4200

  and on the 5300

  That was a lot of combinations

  I can't get a G-connection on 2.45 ghz and only one on the 5 GHz range

  To make things worse, try to call Lenovo is useless without a warranty

  they wont even answer simple questions without it, crazy!

  Have you disabled WMM on the E4200? If you have, then no card Intel and many will fail to connect to any frequency N. For 5 GHz specification requires it to be enabled, but don't really care about many adapters, unfortunately the Intel cards and fail to connect.

• T400: Error Message - there was a problem connecting to the TPM secure

  Hello

  I am a new user of ThinkPad. I just got my T400 a week ago, and I'm a fan of him immediately. But there's this little thing that really bothers me. The second day I used my laptop, I got this error message: "There was a problem connecting to the module of TPM (safety device) on this computer", and I got this message since that date, every time I turn on my laptop.  What it means? And how do I get rid of this error message? Thank you!

  Moderator Note: Type + error message added to the line object for clarity.

  go into the bios and check if the TPM secure is enabled or disabled in the BIOS. Make sure it's on. If the problem persists then call Lenovo, could be a hardware problem.

• Connect two displays high-resolution station dock with T400s

  Hello

  I would like to connect my two DELL 2709W monitors at my station dock with my T400s laptop but the dvi ports do not give me enough resolution. I need 1440 x 900 at the same time.

  Curretly I can get this resolution on one of my monitors via the single HDMI port, I have in the dock station.

  What can I do? Is there for example any graphics card external that I can buy to fix this problem? Or perhaps there is a direct solution?

  Thanks in advance.

  I don't think that the t400s is powerful enough to run two screens wuxga. (but you can check)

• T400 screen flashes when power is connected or disconnected

  Hi guys!

  I recently bought a T400. For the moment, it runs on Windows XP, Service Pack 3.

  After the installation of Windows XP, I installed all the drivers concerned and no yellow question mark appear in Device Manager Panel. However, during the process of installing these drivers, now whenever I plug into our remove the AC power plug, the screen turns off for about a second and then comes back.

  This problem was there immediately after the installation of Windows XP and Service Pack 3, that is before installing the drivers. I think it's a particular driver that may have caused this.

  Could someone help me with this? I tried to reinstall the graphics driver.

  Your video card moves the refresh rate when you change the energy sources.

  See your power manager and video card settings - I bet you on battery, you are ready for 50 Hz and AC, you're ready for 60 Hz.

• T400 stops when connecting VGA monitor

  My T400 stops instantly when I I plug my monitor (Dell WA2209). If I shut down the computer and then try to start the computer with the monitor plugged, the computer shuts down almost instantly after I pressed the power button.  In each case, I have to unplug the computer and remove the battery before I could try and turn on the computer again.  I installed the last Power Manager, video drivers and bios. On the occasion of the strange, I can plug my monitor without the computer stop.  This happens when the use of integrated and discrete graphics.  It worked very well for almost a year and it recently started doing this.  Any ideas?

  Thanks in advance!

• Win 7 slow start - connection with fingerprint reader

  Hello

  I have a T400s (2.4 GHz and 4 GB) with an Intel SSD and WIn 7 RTM with the last drivers beta of Lenovo.

  I have the fingerprint reader enabled for the connection and my startup time of 35 seconds is now shared almost half in the connection of fingerprints and the other half in the rest of the startup procedure.

  Or (the finger) described another way if the machine is turned off and I slide my finger to start the machine, it takes about 17 seconds before the fast logon is indicated.

  Then the machine says 'pending' for 15-20 seconds during which my personal connection icon is flashing by until it ends the connection and almost immediately displays the desktop.

  I am surprised by the very slow connection with my finger already slipped. It would be much faster to turn off fingerprint reader and connect using a password. Someone had this problem and knows how to fix?

  Other problems with the boot, I found (and fixed) is the use of a solid as the Windows background color which, for some reason, costs about 15 seconds at boot time! I also had to reflash the firmware of my SSD to win 10 extra seconds at the beginning of the startup procedure.

  Hello again,

  Sometimes I had to wait several seconds after sliding my finger, to the process of connection of kick. I checked the event viewer on my thinkpad T400 and found the security processes that are at work when loggin. I have excluded them from protection against viruses (Microsoft Security Essentials) and restarted the computer. When the logon screen appeared, I spent my finger and boom, the connection process began immediately.

  Excluded processes are:

  C:\Windows\System32\LogonUI.exe

  C:\Windows\System32\winlogon.exe

• The T400 2768 L 35 WWAN is ready?

  Hi, I bought a T400 2768 L 35 (impossible to find this serial number in the standard list, but that's what it says on the bottom plate of my laptop) my university IT shop a couple of years. I have a 3G compatible SIM card and I would use it on my laptop to surf the net. I found SIM card but did not see any WWAN card in Device Manager. Is there a way I can go online via WWAN? Or am I doomed to rely on wifi

  Welcome to the community.

  as long as it has not changed, this is the hardware configuration for your machine:

  ThinkPad T400 (2768-L35): T9600(2.8GHz), 4 GB of RAM, HD 500 GB at 5400 RPM, LCD 14.1 in 1280 x 800, 256 MB ATI Radeon HD3470, CD-RW/DVD-RW, Intel 802.11agn, option WWAN, Bluetooth, Modem, 1 Gb Ethernet, UltraNav, Secure Chip, reader of fingerprints, camera, 4 c Li-ion, Win7 Pro 32

  the key word above is option. because you do not see a device WWAN in DM, you have probably no card installed. you mention you location SIM, then you probably also have the WWAN antenna, but for sure, you can check if you are comfortable pulling the palmrest and keyboard. Please see the hardware maintenance manual here:

  http://download.Lenovo.com/pccbbs/mobiles_pdf/43y6629_04.PDF / pg100-101.

  If you find the sons of antennas not connected, all you need is a proper map and drivers. the important thing to consider is that the card must be on the BIOS 'white list' trusted network devices. If you scroll down to pg150 of the HMM, you will see the map in the exploded views as ex. No. 25. scroll further down to pgs273-275 who see there are 3 cards listed with their #s FRU. While you are looking to buy, be sure to get a genuine FRU role, rather than a generic/universal model.

  Finally, you can get the driver of the pilot matrix, here:

  HTH a little.

• T400 problem with slow speed internet wireless. Help, please

  Hello

  Just got my new T400 (276581U) and I am very happy with it. However, he has a problem. I searched extensively in this area and other forums, but have not found the solution. So any input or help would be greatly appreciated.

  Problem:
  upload and download speed is very slow when connected to wireless broadband. Measures download speed 1 Mbit/s on www.speedtest.net, while two other computers (XP and Vista) reach speeds 6 Mbit/s on the same network wireless download.

  I tested the computer via LAN and here it downloads at normal speed of 6 Mbps.

  OS: Windows 7
  Network cards:
  Intel 82567LF Gigabit network connection (driver version: 10.1.6.0)
  Intel Wifi Link 5100 AGN (driver version: 13.0.0.107)

  I have download all the latest drivers on the Lenovo support site. The pilot Gigabit Network Connection, I downloaded however Intel, as there is no driver windows 7 on Lenovo website. The Intel driver has improved my connection to the local network (before that I could not download the full site content) and it has not changed my connection Wireless for the better or worse.

  Wireless configuration:
  Wireless g connected to the modem access point high speed
  So, to access internet, I need to connect twice, first the access point, and then click the modem to broadband. This configuration works on two other computers in the House. The lenovo is however not seem to recognize that I am online, even when I am. The symbol "not connected" is always displayed in the toolbar, and diagnostic tests tell me that I'm not online. That might relate to the problem.

  Thanks for reading this. I hope that some kind soul can help.

  pass under the power manager find advanced settings and then look for the Manager of the electric network... its value usually on the default energy savings

• ThinkPad t400 not turn on!

  Help!

  I just poured the water on my thinkpad a little water just for fun, but when I turned it on, it does not fuel upward!
  I'm sobbing on this loss.
  I thought that my thinkpad had also the drainage holes.

  Please help, please help!

  Hi all
  IT'S MY EXPERIENCE THAT IS POURING WATER ON MY T400.
  I got to pour the water on purpose on my Thinkpad T400.
  I'm very young but I just removed the four screws of ram and also removed a screw of keyboard as well.
  I opened the lid, and then I removed the touchpad. Then, I also removed the keyboard. I noticed the water entered the cooling fan and I also found water near the Intel Core 2 Duo processor. I also found water near the hard drive and in the custody of the enclosure, so I removed the Panel silver inside the laptop. I also removed the CD player. I let it dry under a FAN (I did not use a hair dryer, as this may damage the components. Then I put everything back up 3 minutes.i lit .he not even turning on, instead, I hear 1 beep, 3 beeps, 3 beeps 1 beep. I surfed on the internet and found that the error means that RAM is not correct or there is a problem. I still once reassembled RAM as it was before (I changed the arrangement before that caused this error).
  Then, to my surprise I saw Thinkpad on screen and the Windows XP operating system started to load!

  I checked if I had connected the keyboard and the mouse properly. Everything was fine.
  I LOVE MY THINKPAD.

  You can use this method, BUT be extremely careful you don't have static electricity.

  Kind regards

• T400 incredibly slow Windows 7 boot

  Hello

  I came across a problem that I can't bring myself to its cause is a mystery to me:

  I got OEM Vista Ultimate installed on my T400, which worked well, but since I installed Windows 7 today, the windows startup takes unusually long, make me stuck "starting Windows" screen for about 10 minutes each time. Once it starts, it works OK without hiccups or lag whatsoever.

  I have no idea where the root of this problem may be, perhaps this will give you an idea.

  I had two T400 lying around, it had taken defective helmet (stuck somewhere, so the computer assumes that the headphones are always connected, so I could not any sound on the speakers.) As the headphone jack is soldered to the motherboard, I needed to replace the mobo) and the other had it bad LCD. So I decided to use the functional components to build a fully functional T400 and sell the other for parts.

  So what I did:

  -Exchange of the LCD screens (LCD good + good mobo, bad LCD + bad mobo)

  -Exchange processors (because one with defective plug had 2, 53Ghz - anything but the sound was very good! - while the other had only 2, 4 GHz)

  -swapped hard drives (as those with defective jack was the computer I used usually, there were W7 installed, while the other had Vista)

  I put them together and all in one that has Vista booted up quicky as usual (although as before, his mobo was used with a processor more fast and Windows 7), that now with W7 took forever to start up, which has never happened before. I thought it would be because of the CPU (the BIOS reset or disconnect the battery helped CMOS), if I swapped processors once more (-> back to their original mobos). The defective machine with Vista had no problems turning, but it did not help the machine running W7.

  Here is the mystery:

  I swapped hard drives too, so the only change in their original configuration was the display (swapped defective TFT 1280 x 800 for good LED 1440 x 900) and after that two of them were able to start normally.

  But once I erased the disc HARD with Vista on it, which worked very well in the machine where the drive of W7 took forever to start and reloaded Windows 7 at this disk, the problem returned.

  Now I have two T400s with Windows 7, but rather of takes ages to start.

  For the best image:

  T400 No1, original config:	T400 No2, original config:
  Faulty motherboard	Good Mobo
  Good display 1440 x 900	1280 x 800 screen faulty
  PROCESSOR P8700	PROCESSOR P8600
  4 + 2 GB OF RAM	1 + 1 GB RAM
  Intel graphics card	Intel graphics card
  Hard HARD 160 GB w / Windows 7	HDD 160 GB with Windows Vista
  works	works

  T400 No1, current config:	T400 No2, current config:
  Faulty motherboard	Good Mobo
  1280 x 800 screen faulty	Good display 1440 x 900
  PROCESSOR P8700	PROCESSOR P8600

  Intel graphics card	Intel graphics card
  Hard HARD 160 GB w / Windows 7	160 GB HDD with Windows 7, Vista previously
  boots motorcycle quickly	takes forever to start, was OK with Vista

  Please, you have ideas how to redo the slow one usable without going back to vista?

  Any help will be much appreciated, thank you for your patience.

• T400: BSOD with Intel GMA 4500MHD

  Hello

  I own a Lenovo T400 (2767-B44). I am using Windows XP SP3, with the latest drivers on the Lenovo support for this model site

  Recently I tried to use an external display connected to the laptop's VGA connector. It works very well, we can discuss on the quality of the signal. I was using a GPU Intel GMA 4500MHD.

  When I disconnected the monitor windows (without changing the video output for portable TFT only) crashed in a BSOD about two seconds later. I figured that the Intel driver doesn't if I unplug the screen while it is still in use. So I restarted and tried to pass to the output video to portable TFT only before disconnecting. I do not have the option to disconnect the screen, Windows crashed with a BSOD again about two seconds after I changed the video output settings.

  Intel drivers updated to the latest version available on intel.com doesn't change anything.

  Using the ATI GPU, it works very well.

  Any ideas?

  Thank you in advance.

  BTW, are there news about problems with DVI on the T400 port? I'm using linux and I really want to use the DVI port on the Mini with the Intel GPU platform. Intel x.org driver runs a lot smoother than ATI fglrx.

  It turns out that the MS patch has solved the problem.

• Lenovo T400s problems after cleaning

  Hello

  I have a Lenovo T400s, which was full of dust, due to the high temperatures and the slow performance, I decided to clean the cooler all by myself.

  After carefully removing each part, I managed to reach the cooler and clean. I put up successfully each piece of hardware, with the temperature now to a maximum of 70 degrees Celsius in mode performance. Yet, there are a lot of questions that I am yet to repair:

  1. the overall performance of the laptop are slower than before, with the browser and all other apps clearly slowed by something, even after the start of the laptop.

  2. sometimes when I plug in the power cord, the laptop suddenly crashes. It happened to me several times during the loading of the operating system or when I was working on the laptop. After I cleaned up the laptop, I got an error saying "plugged in, not charging", but I fixed it by removing and the battery connection.

  3. the Bluetooth adapter doesn't seem to work. Whenever I try to connect a Bluetooth mouse, the laptop freezes.

  An idea about the origin of these problems and how I could fix them? Thanks in advance.

  I'm under Winodws 8 and the standard hardware configuration of the laptop, with no upgrade.

  
  

• T400 - abrupt shutdown, unbootable

  I have a new T400 (2768GP6) running Windows 7 Enterprise (about 3 weeks). This morning it just turned off all of a sudden and will start. I tried pressing the power button 10 times and holding down on the 11th time without AC or battery connected, but it is just dead. None of the indicators light up when it is connected to the AC.

  I could say that I have the coffee on the keyboard backwards this morning about 5 minutes before it stops. But it was barely a few drops (you know, the few drops remaining while the Cup is technically empty) and I wiped it off with a paper towel. These drops are dumped into the lower left corner, right by the Fn and Ctrl keys.

  Any help is greatly appreciated!

  you have to send it in for repair, but they can charge you for it, if they find any evidence of liquid damage on the motherboard.

  So what you need to do is call Lenovo and upgrade your laptop computer warranty accidental damage protection, which covers the damage incurred by the user as a spillage on the laptop.
